Abstract
Taking the closed circulating water system of a 600 MW power unit as an example, an optimized operation mode was proposed based on the load of steam turbine, the ambient temperature and the relative environment humidity, while a variation law obtained about how the inlet/outlet water temperature of cooling tower in the closed circulating water system (i. e. the outlet/inlet temperature of condenser) change with the unit load, ambient temperature and relative environment humidity by coupling variable conditions of the cooling tower, condenser and turbine. . Results show that with the rise of circulating water flow, the inlet temperature of cooling tower reduces, but the outlet temperature of cooling tower increases, under a certain environmental condition and load; both the inlet/outlet temperature of cooling tower increase with rising ambient temperature, relative environment humidity and unit load.
